How can I get repeatable field values of a Liferay Dynamic Data List via API - field

Question

I try to make a service for reading from Liferay 6.2 DDL.
Here is DDL structure :
<root available-locales="en_US" default-locale="en_US">
<dynamic-element dataType="string" indexType="text" localizable="false" name="Course_ID" readOnly="false" repeatable="false" required="true" showLabel="true" type="text" width="medium">

As you can see I have a repeatable checkbox container, who have 3 more element inside
structure view
I can get and iterate records list, but no idea how can I get a list with all checkboxes and iterate for their elements inside
DynamicQuery getRecordsetIdQuery = DDLRecordSetLocalServiceUtil.dynamicQuery()
.setProjection(ProjectionFactoryUtil.distinct(ProjectionFactoryUtil.property("recordSetId")))
.add(RestrictionsFactoryUtil.ilike("name", courseSetName));
DynamicQuery getDdlRecordListQuery = DDLRecordLocalServiceUtil.dynamicQuery()
.add(PropertyFactoryUtil.forName("recordSetId").in(getRecordsetIdQuery));
JSONArray courseList = JSONFactoryUtil.createJSONArray();
List ddlRecordList = DDLRecordLocalServiceUtil.dynamicQuery(getDdlRecordListQuery);
if (ddlRecordList != null && ddlRecordList.size() > 0) {
int ddlRecordListSize = ddlRecordList.size();
for (int i = 0; i < ddlRecordListSize; i++) {
DDLRecord ddlRec = (DDLRecord) ddlRecordList.get(i);
Field active = ddlRec.getField("Active");
...
Do you can help me with some ideas please ?

I have three fields. solution for how to get repeated Field in portlet.
1.LanguageName (Parent and Repeated Field)
2. DocumentLinkLabel (Repeated Field)
3. DocumentLink (Child Field)
for (JournalArticle journalArticle : journalArticleList) {
Document docxml;
try {
docxml = SAXReaderUtil.read(journalArticle.getContent());
Node root = docxml.getRootElement();
List<Node> languageList = root.selectNodes("/root/dynamic-
element[#name='LanguageName']");
for (int i = 0; i < languageList.size(); i++)
{
Node languageNode = languageList.get(i);
String languageName =languageNode.selectNodes("/root/dynamic-
element[#name='LanguageName']/dynamic-content[#language-
id='en_US']").get(i).getText();
System.out.println("language Name : "+ languageName);
List<Node> documentLinkLabelList =languageNode.selectNodes("dynamic-element[#name='DocumentLinkLabel']/dynamic-element[#name='DocumentLink']");
for (int j = 0; j < documentLinkLabelList.size(); j++) {
Node languageNode1 = documentLinkLabelList.get(j);
String documentLinkName =languageNode.selectNodes("dynamic-
element[#name='DocumentLinkLabel']/dynamic-content[#language-id='en_US']").get(j).getText();
System.out.println(" document Link Lable Name : "+ documentLinkName);
String linkNameList=languageNode1.selectNodes("//dynamic-
element[#name='LanguageName']["+(i+1)+"]/dynamic-
element[#name='DocumentLinkLabel']/dynamic-element[#name='DocumentLink']/dynamic-content[#language-id='en_US']").get(j).getText();
System.out.println(" linkNameList : "+ linkNameList);
}
}
} catch (DocumentException e) {
e.printStackTrace();
}
}

You can't explicitly access DDList content in code. You have to get the xml of the record from the database and use SAXParserUtil and XPath expressions to read the values.
